This week's Tcl-URL

QOTW:   "windows does what windows does." -- Bruce Hartweg

"anything that works is OK with me" -- Cameron Laird


POTW:  Open-source software finds a place in air-traffic control.

    How can untrusted code hurt me? Let me count the ways....
    The "hash attacks" thread spawns a discussion of "command counts"
        <http://groups.google.com/groups?th=ecc3ffda466670d8>
    and a related discussion of "resource limits"
        <http://groups.google.com/groups?th=625f909ed221e321>
    
    Shall the last be first? Could be, since Tcl arrays are unordered!
        <http://groups.google.com/groups?th=a7dddaa3f384b15>
    
    Are you pinin' for APL's iota function?
        <http://groups.google.com/groups?th=c09f8ebedb14adf4>
    
    Your choice of data stucture can make searching easy or hard:
        <http://groups.google.com/groups?th=69de21edd7b751c0>
    
    Getting radiobutton indicators to look just right under Windows:
        <http://groups.google.com/groups?th=b1c0c2e5fe1c8604>
        <http://groups.google.com/groups?th=d0fad35e32eb949a>
    
    Getting the exit code from a system call... truly a FAQ!

Thanks to Arjen Markus for his review of Wiki activity:
  This week a few golden oldies have risen to the surface, together
  with new games and more technical pages, the collection is as 
  varied as we are used to. Here is a summary, coloured by your
  chronicler's interests:
  
  The games:
  
  - Sailing the winds in a light airplane, without leaving your
    comfortable chair, <http://wiki.tcl.tk/9085> 
  
  - Playing with gems and get the highest score sofar! 
    <http://wiki.tcl.tk/9052>
  
  - Perhaps less of a game, but then the computer will do the
    playing instead, <http://wiki.tcl.tk/9047> lets you define
    robots that move along in search of food and light.
  
  Natural language:
  
  - Parsing sentences is explained in <http://wiki.tcl.tk/955>.
    Mind you: just a sketch
  
  - Should we reinvent LOGO? Or simply explore how Tcl can help
    teach programming? Pieces of a discussion at <http://wiki.tcl.tk/9058>
  
  Technical pages:
  
  - An extension for working with red-black trees is available at
    <http://wiki.tcl.tk/5443>
  
  - Using the event loop for multi-tasking: <http://wiki.tcl.tk/8392>
  
  - Here is an interesting idea: use the SDX utility of Tclkit as,
    well, a utility within a starkit. <http://wiki.tcl.tk/9075>
    builds an IDE on this idea (pun not intended).
  
  - The desktop: can it be managed in a Tcl-kind of way? Read all about
    the fragments that could be used at <http://wiki.tcl.tk/1928>
  
  - Those mysterious IP addresses: there is a system to them. 
    <http://wiki.tcl.tk/8909> contains a small tool.
  
  - Producing shaded colours in Tk? <http://wiki.tcl.tk/9079>
    is an elaboration of an earlier page.
  
  - There is a lot more geography done via Tcl than perhaps most of 
    us are aware of - <http://wiki.tcl.tk/736> is a venerable page
    with lots of info.
  

Everything you want is probably one or two clicks away in these pages:
